Description

  The present invention relates to a polishing cover of a polishing apparatus. In particular, the present invention relates to a polishing cover capable of accurately polishing various types of instrument analysis samples for light emission analysis and the like with a polishing apparatus.

  In the steelmaking process of steel production, rapid analysis of samples sampled during steelmaking is important for component analysis. Therefore, it is necessary to measure the sampled sample by instrumental analysis such as emission analysis, but in order to measure with the analytical instrument, the sampled sample surface is polished and smoothed by a polishing device as a pretreatment, and the work is cleaned is necessary. This operation is usually performed by a polishing apparatus having an endless polishing belt rotating at high speed.

  The operator presses, for example, a columnar sample against the polishing belt from the upper side of the travel of the portion where the polishing belt of the polishing apparatus is exposed, to produce a circular smooth surface. At this time, if a uniform force is not applied to the sample, a part of the polishing surface will be caught by the polishing belt, the sample will fly or the polishing surface will be slid, and the skill of the operator is required for polishing, Also, there was a problem in safety because the operator's hand hit the exposed polishing belt.

  As such an improvement measure, for example, Patent Document 1 proposes a polishing machine provided with a sample attaching / detaching portion and a polishing surface adjusting mechanism, and a polishing apparatus in which a rotating and moving mechanism of the polishing machine is attached to a polishing belt. ing. In this device, the sample is attracted to the magnet provided in the polishing machine, and the polishing machine is rotated downward from the rotation center and pressed against the polishing belt, so that the operator does not touch the sample. Then it is safe.

  However, for example, when the height of a cylindrical sample is high, the magnet surface becomes unstable, or when the height of the sample fluctuates, the polished surface is not necessarily perpendicular to the central axis of the sample. Otherwise, there is a risk of polishing obliquely.

Of the metals, it is more preferable to use stainless steel having high corrosion resistance.

  Further, the present invention is characterized in that a stopper for stopping the rotation of the plurality of plate members of the frame member and the cover member at a predetermined angle is provided.

  During polishing work, it is convenient to fix a plurality of plates with a stopper that stops at a predetermined angle, and if there is a stopper that stops at a predetermined angle until the frame member rotates, The entire surface of the polishing belt is exposed, and the polishing belt can be easily replaced or cleaned. The stopper may be attached to the fixing member or may be separately attached to the polishing apparatus.

  With the polishing cover of the present invention, the polishing operation is performed with a minimum exposed portion of the polishing belt, so that the polishing can be performed safely and without any polishing surface. Further, since the frame member and the cover member of the polishing cover can be rotated by the hinge to the fixing member, there is an effect that the polishing belt can be easily replaced and cleaned.

However, the fixing means may be fixed by welding, or may be fixed by other means. The fixing member 2 is provided with fixing member hinge pin holders 26 for fixing the hinge pins 28 at both ends. A frame member hinge 34 of the frame member 3 and a plate material hinge 46 of the plate material 42 of the cover member 4 are attached to the hinge pin 28 so as to be rotatable about the hinge pin 28. In the present embodiment, the fixing member 2 fixes the polishing cover 1 on the polishing belt right cover 16 of the polishing apparatus. However, an L-shaped metal fitting is attached to the side surface of the polishing belt right cover 16 to provide the polishing belt. The width of the right cover 16 may be partially expanded, and the fixing member 2 may be attached thereto. Even when the width of the polishing belt right cover 16 is narrow, the polishing cover 1 can be installed.

  FIG. 2 is a schematic view of a cross section taken along the line AA in FIG. 1. In this embodiment, the fixing member 2 includes a fixing member main body 21 and a fixing member spacer 22. The fixing member main body 21 is provided with fixing member hinge pin holders 26 at both ends, and the fixing member spacer 22 is for adjusting the height of the cover member 4 from the polishing belt 12 and for parallelism. Of course, the fixing member main body 21 and the fixing member spacer 22 may be formed as a single unit.

  As shown in FIG. 1, the frame member 3 is rotatably attached to a hinge pin 28 of the fixing member 2 by a frame member hinge 34, and has a substantially rectangular abrasive belt surrounded by the fixing member 2 and the frame member 3. An exposed part is formed. In the present embodiment, as shown in FIG. 2, the opposite side of the frame member hinge 34 of the frame member 3 is composed of a frame member main body 31 and a frame member auxiliary plate 32. The frame member auxiliary plate 32 is attached to the frame member main body 31 with screws or the like (not shown) on the opposite side of the frame member hinge 34, and is wider than the frame member main body 31, and the lower end of a plate material fixing screw 44 described later. The part is inserted and provided with a hole for engagement. With this configuration, a plurality of plate members 42 constituting the cover member 4 can be engaged with the frame member 3. Further, by adjusting the thickness of the fixing member spacer 22 in accordance with the thickness of the frame member auxiliary plate 32, the height of the plate member 42 from the polishing belt 12 can be adjusted and parallel.

  As shown in FIG. 1, the cover member 4 is covered with a plurality of plate members 42 having a longitudinal direction perpendicular to the traveling direction of the polishing belt 12 (indicated by an arrow) so as to cover the above-described substantially rectangular polishing belt exposed portion. The plurality of plate members 42 are rotatably attached to the hinge pins 28 of the fixing member 2 by a plate member hinge 46 in the longitudinal direction. As shown in FIG. 2, a plate material fixing screw 44 is attached to the opposite side of the plate material hinge 46 of the plate material 42 through the thickness of the plate material 42. As shown in FIG. 3, the plate material fixing screw 44 is grasped. By rotating, it is possible to expose the polishing belt 12 only in the plate material width portion of the plate material 42.

  With this configuration, the polishing operation can be performed with the minimum exposed portion of the polishing belt as compared with the conventional case, which is safe for the operator. In addition, during polishing, even if the polishing sample moves, it is pressed against the plate member 42 or the frame member 3 that covers the exposed portion of the polishing belt in the moving direction and moves little in the moving direction, and the operator applies pressure from above. The polishing operation can be performed without any polishing surface.

  Based on the second embodiment of the polishing cover 1 of the present invention, the operation process will be described. As shown in FIG. 4, in the second embodiment, the polishing cover 1 is further provided with a stopper 50 that stops the rotation of the plate members 42 of the frame member 3 and the cover member 4 at a predetermined angle.

  In the present embodiment, the stopper 50 is provided in parallel to the fixing member 2 and is fixed on the polishing belt right cover 16 with a stopper fixing screw 52. The stopper 50 can be directly attached to the side surface of the polishing belt right cover 16, and when the L-shaped metal fitting is attached to the side surface of the polishing belt right cover 16, and the fixing member 2 is attached to the metal fitting, The stopper 50 can be moved in the vertical direction, and the height adjustment can be easily made variable. As shown in FIG. 5, the stopper 50 rotates the plate members 42 of the frame member 3 and the cover member 4 to the fixed member 2 by the frame member hinge 34 and the plate member hinge 46. Can stop at an angle. A broken line indicates a state where the rotation is stopped by the stopper 50. Note that a round wire coil spring (not shown) is used for the plate hinges 46 of the plurality of plate members 42 of the cover member 4 so that the relative angle between the fixing member 2 and the plurality of plate members 42 of the cover member 4 is 90 degrees. If it is within the closing direction, and if it exceeds 90 degrees, it will be opened more easily.

  First, at the start of work, the polishing cover 1 covers most of the exposed portion of the polishing belt 12. When the worker rotates the frame member 3 to the stopper 50, the plurality of plate members 42 of the cover member 4 also rotate to the stopper 50 at the same time. As a result, the polishing belt 12 is released. An abrasive sample S is placed on the opened abrasive belt 12. This time, the frame member 3 is returned so as to cover most of the exposed portion of the polishing belt 12. The plurality of plate members 42 of the cover member 4 also rotate and follow together with the frame member 3 by the force of the round coil spring, but only the portions of the plurality of plate members 42 that contact the polishing sample S are shown in FIG. As shown, it is in a raised state.

  In this state, the plurality of floating plate members 42 are rotated to the stopper 50. Then, as shown in FIG. 7, the polishing belt 12 is exposed only in the plate material width portion of the plurality of plate materials 42 corresponding to the polishing sample S, and the polishing operation is performed with the minimum polishing belt exposed portion necessary for the polishing operation. Can do. Since the relative angle between the fixed member 2 and the plurality of plate members 42 rotated to the position of the stopper 50 exceeds 90 degrees, the plurality of plate members 42 are always pressed against the stopper 50 by the force of the round wire coil spring. Thus, the plurality of plate members 42 do not return to the original state due to vibration or the like during the operation.

  When the operator lifts the polishing sample S and presses a rotation start button (not shown) of the polishing belt 12, the rotation starts and the polishing operation is performed with the minimum necessary exposed portion of the polishing belt, which is safe. In addition, during polishing, even if the polishing sample S moves, it is pressed against the plate member 42 or the frame member 3 that covers the exposed portion of the polishing belt 12 in the moving direction and moves little in the moving direction, and the operator presses from above. Polishing work can be done without any polishing surface.

  When the work is finished, the polishing sample S is lifted and the rotation stop button of the polishing belt 12 is pressed to stop the rotation. When the operator returns the plate member 42 rotated to the position of the stopper 50 to the frame member 3, the operation returns to the work start state, and the polishing cover 1 covers most of the exposed portion of the polishing belt 12.

  With the polishing cover 1 of the present invention, the polishing operation is performed with a minimum exposed portion of the polishing belt, so that it can be performed safely and without any polishing surface.
